The article presents the results of studying effect biological preparations created on basis such living microbial strains as Bacillus subtilis (Naturost), Lactobacillus buchneri (Naturost-Active) and megaterium (Naturost-M) productivity nutritional value clover timothy mixture. We conducted a microplot experiment at Vologda Research Center Russian Academy Sciences (Vologda Oblast) in 2019–2021...

Enset (Ensete ventricosm) is a multipurpose crop serving millions of Ethiopians as an alternative food source. However, the traditional kocho preparation labor-intensive and results in poor quality. This study evaluated Purdue improved storage (PICS) bag to underground pit for fermentation. The experiment was arranged factorial design with two fermentation systems (underground PICS bag) three t...

Rumen is a persistent and specific ecosystem consists of bacteria, protozoa and fungus where feed fermentation takes place in it. Produced Hydrogen in rumen can be used in the synthesis of the volatile fatty acids and the microbial protein and its excess would be eliminated through the production of Methane by methanogenesis. Nutritionists have tried to find ways to decrease loss and energy and...

Although methanogenic degradation of hydrocarbons has become a well-known process, little is known about which crude oil tend to be degraded at different temperatures and how the microbial community is responded. In this study, we assessed the methanogenic crude oil degradation capacity of oily sludge microbes enriched from the Shengli oilfield under mesophilic and thermophilic conditions. The ...

Microbial biomass having 46% crude protein content and enriched with essential amino acids as well as extracellular xylanase activity (100-150 IU/ml) was produced by an efficient fungal strain, Penicillium janthinellum (NCIM St-F-3b). Optimization studies for maximum xylanase and biomass production showed that the fungus required a simple medium containing bagasse hemicellulose as carbon source...

an experiment was conducted to evaluate the effects of microbial phytase on apparent digestibility of crude protein (cp), amino acids (aa), and apparent retention of calcium (ca), total phosphorus (tp), iron (fe) and zinc (zn) in female broiler chickens diet. the experiment was designed as a completely randomized design. each treatment consisted of 4 replicates of 10 broilers in battery cages, ...

it has been known for years that microbial surface active agents have a wide range of applications not only in oil spill environment but also in many industries. their properties including: (i) changing surface active phenomena, such as lowering of surface and interfacial tensions, (ii) wetting and penetrating actions, (iii) spreading, (iv) hydrophylicity and hydrophobicity actions, (v) microbi...

The objectives of this study were to investigate the effects of dietary crude protein (14.5 or 12.0%) and cellulose (8.7 or 2.5%) levels on composition of feces and manure after 8 wk of diet feeding and storage. Pigs were fed twice daily; after each feeding, urine and feces were collected and added to manure storage containers. On weeks 2 and 8 after initiation of the experiment, fresh fecal an...
